How Long Does Milk Last?

How long does milk last? Milk is a dairy product produced by mammals such as cattle, goats and sheep. It comes in a variety of types (whole milk, reduced fat, skim and non-fat milk) and can be processed into other dairy products such as yogurt, butter and cheese. Studies suggest that, as a result of its high vitamin content, consumption is effective in promoting muscle growth and improving post-exercise muscle recovery. From the full taste and high cream content of whole milk to the skim and non-fat versions (which actually help when on a weight loss diet), it provides the body with much needed calcium and vitamin D to name a few. However, it is more fragile than most people realize. The shelf life of milk is influenced by a variety of factors, such as processing method and carton date, exposure to light and heat, and how it is stored.

So, how long does milk last? When properly stored at or below 40°F, containers of milk last for the time periods past the date printed on the carton as indicated in the table below:

Milk Expiration Date

(Unopened) Refrigerator
Past Printed Date
Lactose-Free Milk lasts for 7-10 Days
Non-Fat Milk lasts for 7-10 Days
Skim Milk lasts for 7 Days
Reduced-Fat Milk lasts for 7 Days
Whole Milk lasts for 5-7 Days
(Opened) Refrigerator
Past Printed Date
All Milk lasts for 5-7 Days

Of course, all types of food and drink products last for a shorter period of time if they are not stored properly. But remember, dairy products usually have a sell by date - which is the last date by which a manufacturer will vouch for a product's quality, not its safety. Because of this distinction, you may safely use it to compliment your favorite meals even after its "sell by date" has lapsed, according to the table above if it is stored properly at all times.

How to tell if Milk is bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent food born illness.

Although not a perfect test, your senses are usually the most reliable instruments to tell if your drink has gone bad.

Some common traits of bad milk are discoloration, lumpy texture and a very distinctive unclean sour smell (which you will notice when removing the lid). These changes occur from lactic acid producing bacteria.

If you have sour milk, check our substitute page to find a proper alternative.

There are, of course, certain health risks associated with spoiled foods, so always remember to practice food safety and enjoy your foods before their shelf life has expired!

How to store Milk to extend its shelf life?

Keeping milk cold is essential to extending it's shelf life. You can help keep milk fresh longer by keeping it away from light and by placing it back in your refrigerator immediately after each use. Store milk on an interior refrigerator shelf rather than in the door, where the temperature fluctuates with frequent opening. In addition, opened milk should be stored tightly in its original container as the containers were specifically designed for this purpose.

Unfortunately, freezing milk, although safe, isn't a great option. Freezing is not recommended because freezing destabilizes the molecular structure and the resulting product will be less desirable than the fresh product. If you do freeze your milk it will keep for about 3 Months in the freezer. When thawed, the texture and color will be altered, it will be lumpy and yellow but the product will remain safe.

Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.

How to use extra before your Milk goes bad?
